Nivolumab-induced small bowel obstruction and perforation: a rare but life-threatening side effect of immunotherapy
Emergency Radiology - Tập 27 - Trang 107-110 - 2019
We present a case of a 58-year-old female with anti-PD-1 immunotherapy-related small bowel perforation. The patient was on long-term therapy with nivolumab for metastatic non-small cell lung cancer. She presented to the emergency department with acute abdominal pain, in which the CT revealed a short segment of dilated distal ileum proximal to a very short segment of bowel with mural thickening and...... hiện toàn bộ
Signal-to-noise ratio and dose to the lens of the eye for computed tomography examination of the brain using an automatic tube current modulation system
Emergency Radiology - Tập 24 - Trang 233-239 - 2016
The study aimed to evaluate the image quality in terms of signal-to-noise ratio (SNR) and dose to the lens of the eye and the other nearby organs from the CT brain scan using an automatic tube current modulation (ATCM) system with or without CT gantry tilt is needed. An anthropomorphic phantom was scanned with different settings including use of different ATCM, fixed tube current time product (mAs...... hiện toàn bộ
Musculoskeletal: what is different in children? Falling on outstretched upper extremity: diagnosis by serendipity
Emergency Radiology - Tập 17 - Trang 259-260 - 2010
Magnetic resonance imaging versus computed tomography and ultrasound for the diagnosis of female pelvic pathology
Emergency Radiology - Tập 28 - Trang 789-796 - 2021
We sought to determine the diagnostic accuracy of magnetic resonance (MR) imaging compared with computed tomography (CT) and ultrasound (US) when evaluating for five common pelvic pathologies among women presenting to the emergency department (ED) with right lower quadrant abdominal pain. This prospective, single-center study was conducted at an academic ED as a sub-analysis of a direct comparison...... hiện toàn bộ
Accuracy of CT angiography for the diagnosis of vascular abnormalities causing intraparenchymal hemorrhage in young patients
Emergency Radiology - Tập 16 - Trang 195-201 - 2009
The objective of this study is to measure the accuracy of multidetector CT angiography (MD CTA) in the detection of vascular abnormalities in patients ≤40 years with spontaneous intraparenchymal hemorrhage (IPH) presenting to the emergency department. After institutional review board approval, a retrospective study was performed of 43 consecutive patients ≤40 years, who presented to our emergency ...... hiện toàn bộ
Head CT evaluation in clinically stable motor vehicle collision patients
Emergency Radiology - Tập 11 - Trang 328-335 - 2005
Purpose: To assess the utilization of non-contrast head computed tomography (HCT) in clinically stable patients who were involved in motor vehicle collisions. Our goal is to identify patients in whom HCT may be safely excluded without altering clinical outcome. Methods: Adult, front-seat passengers were retrospectively examined. All clinically stable patients involved in motor vehicle collisions a...... hiện toàn bộ
Abdominal gunshot wounds: multi-detector-row CT findings compared with laparotomy—a prospective study
Emergency Radiology - Tập 19 - Trang 35-41 - 2011
The purpose of this study was to access the accuracy of multi-detector-row computed tomography (MDCT) in diagnosing injuries in hemodynamically stable abdominal gunshot wound victims (AGWV). Triple-contrast MDCT was performed in hemodynamically stable AGWV during a 20-month prospective diagnostic accuracy study. Thirty-one patients (30 males, 1 female; mean age, 24.3 years) were evaluated by two r...... hiện toàn bộ
Magnetic resonance imaging of acute orthopedic trauma to the lower extremity
Emergency Radiology - Tập 4 - Trang 30-37 - 1997
This article reviews the role of magnetic resonance imaging in evaluating suspected or known lower limb fractures of the hip, knee, ankle, and forefoot.
Beyond acute appendicitis: imaging and pathologic spectrum of appendiceal pathology
Emergency Radiology - - 2014
While acute appendicitis is a common and important clinical problem, a variety of other disease processes can affect the appendix. Simple and perforated appendicitis, tip appendicitis, and stump appendicitis share a common clinical presentation including anorexia, right lower quadrant pain, and fever. By imaging, most cases of acute appendicitis exhibit luminal dilation, wall thickening, and peria...... hiện toàn bộ
Ultrasound in acute trauma of the ankle and hindfoot
Emergency Radiology - Tập 9 - Trang 283-288 - 2002
Ultrasound is a rapid, widely available and inexpensive imaging modality for the evaluation of the ankle and hindfoot. Ultrasonography can be performed in acute, semiacute and chronic conditions. Ankle injuries can be evaluated with ultrasound combined with X-rays. In the emergency room, acute trauma of ankle and hindfoot is an important indication for ultrasound.
